Abstract (en)
[origin: EP2361765A1] First and second piezoelectric layers (17a,17b) are stacked from a side closer to an opening of a liquid channel formed in a channel member (12) in this order, and are sandwiched between electrodes (18,19,20) with respect to a stacking direction. A driving-signal generating section generates an ejection driving signal for ejecting droplets from an ejection port and a non-ejection driving signal for vibrating a meniscus formed in the ejection port without ejecting droplets from the ejection port. A voltage applying section applies, based on image data, a voltage corresponding to the ejection driving signal to one of the first and second piezoelectric layers, and applies a voltage corresponding to the non-ejection driving signal to another one of the first and second piezoelectric layers during a period in which the voltage corresponding to the ejection driving signal is not applied to the one of the first and second piezoelectric layers.
